Mnemonic description of song:
ee-oh-lay (flute-like – last note trilly)
oo-duh-lay-oh or oodle-drrrr (last note trilly)
What do we know about wood thrush song?
- 3-part song: 1st part is short, low in pitch and quiet, 2nd part is flute-like and loud, 3rd part is trill-like (Borror and Reese 1956b, Stein 1956)
- Ventriloquist properties
- 1-3 variations of 1st-part of song, 2-8 of central part and 6-12 of last part (Borror and Reese 1956b ,Whitney 1985)
- Create different songs from various combinations of the parts (Borror and Reese 1956b)
- Countersings, but avoids answering with identical songs (Kroodsma 2005)
- Females may sing (Brackbill 1958)
How and when is song acquired?
- Learn central, flute-like part of song, 1st and 3rd part not learned (Lanyon 1979a)
- When young isolated from song, central part develops abnormally (Lanyon 1979a)
- When tutored with recorded central phrases, develop songs with those phrases (Whitney 1985, Whitney and Miller 1987)
What can we do to facilitate learning?
Expose to adult singing
Play recordings of song as playing them has been shown to be effective.
